The features of exhaust air relief valve

1. Exhaust process more smoothly

Steady air release can avoid pressure surge and protect pipeline damage.

2. More autonomous working mode

The air relief valve can release air when filling water in pipe, enter air to get rid of negative pressure when vacuum or negative pressure exists.

3. More reliable way of discharge

Quick released air and air with water will not close valve orifice in advance and cause air seal. Orifice will close when air is released completely.

4. Automatic protection safer performance

Whenever if system pressure is lower than atmosphere, water column happened, the air relief valve will open immediately and air will enter system to get rid of negative pressure, at the same time, entering air can speed up the speed of air release during air release.

Product Parameters

TWT Exhaust air relief valve can be divided into:

High speed compound air release valve

Slow closing inlet and outlet air relief valve

Size: DN25-DN300

Pressure: PN1.0-1.6Mpa

Temp: 0ºC-90ºC

Main materials: cast iron, ductile iron, stainless steel

Connection type: Thread, Flange

Inspection and maintenance program:

Close cut-off valve under air release valve

Take off the connection bolts between valve body and cover, use water to clear floating ball, body, cover, sealing ring and screen

The floating ball is put back in place, install the valve cover, tighten the bolts

Open the cut-off valve

Installation and maintenance:

Valve should be installed vertically in the pipeline highest point

The cut-off valve (butterfly valve or gate valve) should be installed before air release valve

Check and maintenance is recommended for one or two times in one year, the work can increase according to water condition
